What is the current status of the new atomic load/store lowering started in https://reviews.llvm.org/D69219? <https://reviews.llvm.org/D69219?> The main reason atomic stores currently don’t work in GlobalISel is because the operands for atomic store are backwards from a regular store. Can we invert the operand order of the pattern nodes yet? That would avoid the need to handle the special case in TableGen.
